ABSTRACT:
In geological exploration, an improved optical reflectance includes a coating consisting of micropulverized PTFE powder and cement having similar spectral characteristics to the powder. The coating is bonded to a substrate and the surface of the coating is milled to a matte surface having uniform reflectance characteristics, including Lambertian response.
